Hello to all who have experience some kind of "communication error" that renders videoconferences inoperative.

I have found a possible cause and a solution. At least to my problem. I had videoconferences on my Mac Pro without any problem and then all of a sudden, it seemed, it wouldn't work and I got the above mentionned message.

In fact here is what happened:

I originnaly used my mac with the ethernet port. Everything was fine. Then I went to a wireless connection with the use of an "Airport extreme" base station(the one with airtunes)plugged to my router and, still, everything was fine.

However, at one point I repluged the wire and kinda used both. That 's where the error originated.

Indeed, in that kind of setup, you have to make sure that "Network port configuration" will show "Airport" as the first choice. In my setup, if it's set to "Built-in ethernet 1" and then "Airport", even though both are plugged, I will get the error message.

I hope this is clear enough to help anyone with that problem.
